Personally I am :
- Extraordinarily content with a full 8 hours, which almost never happens
- Fine and dandy with 7
- Fully functional with 6
- Grumpy with 5
- Zombie-like with 4
- Barely able to keep myself upright with 3.

But, as the article says... you do you.

By using objective measures such as actigraphy, which monitors activity and rest cycles, he and other researchers have found that people from hunter-gather societies typically get between 5.7 and 7.1 hours of sleep per night – on the lower end of the scale compared to industrial societies. Their sleep is also more fragmented.

But it also doesn't bother them, says Samson. Of two groups he looked at, in Namibia and Bolivia, less than 3% of foragers said they had trouble falling, or staying, asleep – a fraction of the up to 30% reported in industrial societies. Neither group had a word for "insomnia" in their languages.

"We have this narrative in the West [that] humans have never been more sleep-deprived," he adds. It's total rubbish, he says.

"Sleep need should be regarded as dynamic, with the potential to adapt in response to environmental circumstances," the researchers write. "This means that there is not an optimal amount of sleep for an individual across situations and times. Rather, sleep is a negotiable quantity that is affected by environmental, cultural, psychological and physiological factors, which must be balanced against competing needs and opportunities for various behaviours."
